TECHNICAL FIELD

The present invention generally relates to a liquid topical pharmaceutical composition for the treatment of various wounds in human skin. The invention belongs to the surgical field of combined traditional Chinese and western medicine.

BACKGROUND

Repairing and healing of various skin wounds in human is a complex pathophysiological process. Slight and fine wounds undergo wound bleeding or exudation, dry scab, and healing under scab. Most of the relatively large or special skin wound (such as burns), after the injury, would experience exudation, infection, necrotic tissue clearance, infection control, wound exudation reduction, scabbing or wound coverage by biomaterial materials and wound healing of scar.

During the complex healing process in skin wounds, in addition to systemic treatment, one of the most important steps in wound treatment is the choosing of medicine for wounds. Currently there are various pharmaceutical preparations for treating skin wounds, which generally consist of suspensions, ointment, disinfectant and film forming agent. Those skilled in the art will appreciate that, although these types of wounds medications are effective, there are certain limitations existing in clinical treatment of skin wounds.

As mentioned above, among the applicable pharmaceutical preparations for treating skin wounds, for example, when a suspension is used, a large quantity of dressing is required to wrap the wounds, and the dressing would often stick to the wound surface after drying of the pharmaceutics, which makes new tissue tearing in wounds and causes bleeding during dressing replacing, prolongs the time of dressing replacing and increases the workload of medical staffs. For example when an ointment is used, the ointment would be incompatible with the wound exudation. Ointment is easy to flow in the case of more exudation of the wound surface, and also causes the adhesion between the dressing and wounds, which makes it difficult for dressing replacing. Film forming spray could seal the wounds better, however could not quite resolve the problem of the adsorption of wound exudation, therefore easily produces submembrane empyema.

The Chinese medicine believes that, “the river protects the grass and wood, and the Qi and blood protect the skin”. The repairment of skin wound requires sufficient support from Qi and blood of human body, just as the grass and wood can't live without water and soil. Chinese medicine Astragali Radix, Angelicae Sinensis Radix, Salviae Miltiorrhizae Radix et Rhizoma and Paeoniae Radix Rubra are beneficial for the Qi, activate the blood, eliminate swelling and relieve pain, therefore the skin grows when Qi and blood are circulating.

Coptidis Rhizoma, Scutellariae Radix, Phellodendri Chinensis Cortex and Gardeniae Fructus are from the famous ancient prescription “Coptidis Decoction for Detoxification”, which is recorded in Ge Hong's “Handbook of Prescriptions for Emergency” in East Jin dynasty and Wang Tao's “Medical Secrets from the Royal Library” in Tang dynasty, and usually internally used for treatment of various sores, ulcer and fire-toxicity by later physicians. It is frequently seen in the modern medical journals that Coptidis Rhizoma, Scutellariae Radix and Phellodendri Chinensis Cortex are fried or mixed with sesame oil and dressed to the wounds of burns and scalds. All the pains, itches and sores belong to the heart, and Scutellariae Radix purges fire of lung heat from the upper energizer, Coptidis Rhizoma purges fire of heart and stomach heat from the upper middle energizer, and Phellodendri Chinensis Cortex purges the kidney fire from the lower energizer. According to “the meaning of medicines”, Phellodendri Chinensis Cortex purges fires everywhere from the top to the heels of feet and from the skin to the bone marrow, and Gardeniae Fructus purges fire of all three energizers. In that case, the fire-toxicity all over the body could be reduced to the end of the flow and there will be no burst sore. Modern researches have found that this decoction has the functions of degrading endotoxin, modulating immunoresponse, protecting brain, liver, kidney and intestinal mucosa and capillary and anti-apoptosis, and anticoagulant and anti-thrombosis.

Ampelopsis Radix is heat-clearing and detoxifying; Ilex purpurea Hassk is heat-clearing and detoxifying; astringing dampness and furuncle, and blood-cooling and blood-stanching; Bletillae Rhizoma is astringing dampness and furuncle; Glycyrrhizae Radix et Rhizoma harmonizes the herbs and is detoxifying and anti-inflammation, together with Astragali Radix, Angelicae Sinensis Radix, Salviae Miltiorrhizae Radix et Rhizoma and Paeoniae Radix Rubra, nourishes living cells of wounds

Olibanum tends to promote Qi and open orifices and Myrrhaa tends to regulate blood and remove blood stasis. Olibanum and Myrrha have spicy dispersions and are important medicines for deportation of Qi stagnation and blood stasis. By circulating Qi and activating blood, swellings of big sores can be eliminated, so as to promote repairment of the local injuries. The swelling elimination and tissue regeneration functions of Olibanum and Myrrha can hardly be replaced by ordinary medicines.

Draconis Sanguis relieves blood pain and is a great medicine for blood harmonization. It specifically and greatly works in blood aspect, while Olibanum and Myrrha are mainly for blood illness, but they also work in Qi aspect. Draconis Sanguis is an important medicine to remove blood stasis and produce new blood. It mainly works in eliminating blood accumulation, treating metal-inflicted wound, killing pain, which is immediately effective when applied alone, or works better in removing blood stasis and activating blood when applied together with Olibanum and Myrrha. These three medicines can stop bleeding without leaving stasis and active blood so as to stop the pain, therefore they are considered as the three musketeers in blood illnesses, and wherever there is blood stasis, they can activate the blood and kill the pain. Catechu can remove the scab in addition to antibacterial and restraining functions.

There are dozens of medicinal materials for the treatment of the sore department recorded in the traditional Chinese medicine literature, and the above-mentioned sixteen kinds of Chinese medicinal materials are scattered in various prescriptions, which are only used as a component for the preparation of soups, powder (powders) and ointments. The limitations of these dosage forms in the treatment of burn wounds have been previously described.

In fact, an ideal wound medicine should be characterized as easing pain, fast wound sealing, absorbing wound exudation, reducing exudation, facilitating drainage, protecting wound area, promoting the growth of epithelial cell on wound area, broad and strong antibacterial effect, no production or low production of drug-resistant strain, toxin-free, few side-effects and few scars after wound healing. Therefore, the problem to be solved by the present invention is to find a convenient and highly efficient topical fluid pharmaceutical composition to treat various skin wounds, with the use of important raw materials and the combination of Chinese and Western medical ideas, and with ideas different from the past, to prepare the pharmaceutical composition using a specific method, so as to meet the requirements for an ideal wound preparation as far as possible.

SUMMARY OF THE INVENTION

This invention firstly emphasizes that an important component in the pharmaceutical composition of the present invention consists of glycerol, 1,2-propanediol, water-soluble Laurocapram or decyl methyl sulfoxide and water in a specific ratio. When used alone to treat various skin wounds, the important component could rapidly seal the wound area, absorb wound exudation, forms a transparent thin scab and resist the invasion of outside bacteria. When used in fine combination with a selection of pharmaceutical composition, they present a lot of ideal therapeutic effects! The biggest characteristics of the present invention are the important component and the specific ratio thereof.

Human body is an organism, whose periphery is fully covered by skins, and achieves metabolism and life maintenance through exchange materials with outside environment through blood circulation and body fluid exchange, which makes the minimal unit of the organism, i.e. every living cell exchange materials with outside in a completely closed and relatively constant environment. Skin injuries due to various reasons will cause the exposure of tissue cells that are previously protected by the skin and the “disaster” in local injured area. The body will recruit limited forces to the injured part to do emergency rescue, which leads to a series of pathophysiological alterations in the injured area. Because of the limited defective force the body could mobilize and the large wound area, the body has to rely on the outside medical aids. When facing the multiple skin wounds, doctors will firstly make the wound area restore the completely sealed state rapidly and be isolated from the surrounding air, then reverse the pathological alterations in the wound area such as hemostasis, anti-exudation, swelling subsidence and sterilization to promote the physiological repairment of wounds so that the multiple skin wounds could overcome the “disaster” smoothly and restore the normal states. The referred “the first priority in treating various skin wounds is to seal the wounds rapidly and completely” has been emphasized in none of the current literatures. It is due to the thorough observation and thinking of this statement, the inventor has performed serious practice repeatedly, and found out and selected glycerol, 1,2-propanediol, water-soluble Laurocapram or decyl methyl sulfoxide and a small amount of water in a specific ratio to be the basic medicine matrix of the pharmaceutical composition of the present invention, and formed pharmaceutical composition by accompanying selected Chinese medicinal herbs in order to thoroughly excavate the functions of four substances that constitute the basic medicine matrix, and achieved the present invention. The multiple skin wounds cannot be dressed with obvious stimulating medicines that cause re-injury of the tissue cell in wounds. The basic medicine matrix in this invention can not only fulfill the above-mentioned requirements, but also extract the effective medicinal ingredients of Chinese medicinal herbs to absorb water-dampness, stop exudation, promote penetration, make thin scabs, activate Qi and blood, dredge collateral, provide nutrition and promotes regeneration. All of the above are beneficial actions to promote wound healing and reduce scars.

The invention discloses a pharmaceutical composition for treating various skin wounds, wherein the important components of the present pharmaceutical composition comprises glycerol, 1,2-propanediol, water-soluble Laurocapram or decyl methyl sulfoxide, and water in a specific ratio, wherein the glycerol is present in the composition in an amount of 80% to 90% by volume.

The effective components of Chinese medicinal herbs in composition of the present invention are extracted by solvent glycerol or 1,2-propanediol. Under room temperature, the effective components of Chinese medicinal herbs have low solubility in glycerol and precipitate slowly. The applicant has found that given proper pressure, temperature and certain time, the effective components of Chinese medicinal herbs have good solubility in glycerol by adding a small amount of water into glycerol. The boiling temperature of glycerol is 290° C. . In practice, the hydrated glycerol is heated up to 105° C. by high pressure steam from separation layer and maintained for 10 min. The selection of such temperature and time is to maintain the chemical stability of glycerol and to dissolve the effective components of Chinese medicinal herbs ideally.

1,2-propanediol has relative low proportion in the common components of the composition, however, the amount used is enough as a solvent for soaking and extracting pharmaceutically effective components of Olibanum, Myrrha, Draconis Sanguis and Catechu in composition.

Following the principles of traditional Chinese medicine surgery of clearing heat and detoxicating, activating blood and removing swelling, removing putrefaction and promoting tissue regeneration, and astringing dampness and furuncle, with the thought of “complemented by clearing and dredging, nourished by dredging, balanced by nourishing and purging and treated by both dredging and nourishing”, the present invention makes a new big prescription consisting four medicine matrixes with many varieties and light doses from Astragali Radix, Angelicae Sinensis Radix, Salviae Miltiorrhizae Radix et Rhizoma and Paeoniae Radix Rubra; from Scutellariae Radix, Phellodendri Chinensis Cortex and Gardeniae Fructus; from Ampelopsis Radix, Ilex purpurea Hassk, Bletillae Rhizoma and Glycyrrhizae Radix et Rhizoma; and from Olibanum, Myrrha, Draconis Sanguis and Catechu. With the addition of a basic medicine matrix capable of adsorbing dampness, keeping moisture, forming membrane and being solvent, the five medicine matrixes work together, with comprehensive theories and appropriate prescriptions, and create a new preparation, which is repeatedly and effectively used in clinical practice by the inventor.

With respect to structure of the prescription, macroscopically, the first medicine matrix herbs Astragali Radix, Angelicae Sinensis Radix, Salviae Miltiorrhizae Radix et Rhizoma, and Paeoniae Radix Rubra are part of monarch, nourishing Qi and blood and expelling toxins from within body; the second medicine matrix herbs Scutellariae Radix, Phellodendri Chinensis Cortex and Gardeniae Fructus are part of minister, clearing toxins and purging fire; the third medicine matrix herbs Ampelopsis Radix, Ilex purpurea Hassk, Bletillae Rhizoma, and Glycyrrhizae Radix et Rhizoma are part of assistant, astringing dampness and furuncle and removing swelling; the forth medicine matrix herbs Olibanum, Myrrha, Draconis Sanguis and Catechu are part of guide, promoting Qi, activating blood, dredging collateral, removing putrefaction and promoting tissue regeneration.

Example 2 Clinical Verification of Pharmaceutical Composition Formulation 4 For Treating Sutured Wound After Skin Incision

Formulation 4 in table 1 is an important component in the pharmaceutical composition of the present invention, and consists of glycerol, 1,2-propanediol, water-soluble Laurocapram, and water in specific ratio. The traditional treatment after suture of skin incision wound is to cover the wound with 75% alcohol gauze. The following is the clinical comparative observation using pharmaceutical composition Formulation 4 of the present invention and using traditional alcohol dressing for treating sutured wound after skin incision.

1) General Information:

Totally 50 cases after aseptic operation were selected, aged between 20-60 years old, among which 40 men and 10 women were divided into treatment group and control group. The length of skin incision was more than 8 cm in average.

2) Treatment Method:

a. Treatment group: After suturing, cleansing and disinfection of the skin incision, apply Formulation 4 onto the wound stitch with cotton ball, cover the wound stitch with sterile gauze after 1-2 min and fix with adhesive tape. Apply Formulation 4 once on day 2 when change the wound dressing and again on day 7-8 after removing the suture in time to seal the stitch.

b. Control group: After suturing, cleansing and disinfection of the skin incision, dress the wound stitch with 75% alcohol gauze, cover with sterile gauze and fix with adhesive tape. Change the wound dressing on day 3, when there were signs of infection in a small number of cases, and change the dressing every day until the wound is healed.

3) Evaluation Criteria of Therapeutic Effect

Evaluate the therapeutic effect from day 3 after wound suture to day 7 after suture removing, according to the wound healing state and inflammatory response on the stitch.

a. Excellent healing: scab on wound stitches after 3 days, no or few exudation, little dressing stains on wound. 7 days after operation, wound healed at I grade and little inflammatory response on the stitch.

b. Good healing: little exudation on wound stitch after 3 days, obvious stains on wound dressing. The exudation gradually reduced after applying iodine and change the wound dressing every day for consecutive 3 days and the scab gradually formed on wound stitches. Usually the suture was removed 8-9 days after operation, wound healed at I grade and there was congestion and redness on stitches.

c. Poor healing: wound exudation on day 3 when changing the dressing on stitch, slightly damp dressing, redness on stitches and removing of sutures at intervals was required to facilitate the drainage of wound exudation. Change the dressing every day. Prolonged wound healing.

4) Treatment Results (See Table 2)

5) Discussion

The clinical comparative observation and quantitation result in table 2 showed that the therapeutic effect of pharmaceutical composition Formulation 4 of the present invention in treating sutured wound after skin incision is better than the traditional treating method which covers the sutured wound with 75% alcohol gauze. This is because the alcohol is volatile disinfectant although it kills bacteria. If 75% alcohol gauze is used for wound dressing, there will only be gauze left in a few hours after the alcohol gets fully volatilized. If the patient is not well cared for, the bacteria can easily invade the wound stitch from the edge of the gauze, causing varying degrees of wound infection. The components in pharmaceutical composition Formulation 4 of the present invention are mainly glycerol and 1,2-propanediol which are not volatile, and can rapidly and completely seal wound stitch after contacting it, absorb a small amount of exudation on wound stitch, form a transparent layer of scab by binding with proteins in the exudation, and protect the wound from the invasion of outside bacteria closely to make the wound stitch clean and dry and achieve good healing.

Example 3 Clinical Observation of the Wound in Burned Patients Treated with the Pharmaceutical Composition

According to the pathophysiological healing mechanism of various skin injuries, the skin injuries caused by burns are the most serious, complex and representative one. The inventor illustrates the therapeutic examples of the invented pharmaceutical composition on skin wound treatment using burn wound as a model.

The principle of dealing and treating burns is early prevention and the treatment of shock. The important step in treating burns is the short course application of sufficient and highly effective antibiotics and treating burn wounds scientifically during early stage, therefore makes the wound tightly covered and reduces the wound exudation, i.e. reduces patient's physical consumption, keeps the wound dry, makes the broad-spectrum antibiotics reach the deep part of the wound, protects the residue epithelial germinal cells from free radicals, oxidation and apoptosis and promotes wound healing.

One pharmaceutical composition of the present invention for treating various skin wounds is designed according to the above requirements for treating wounds. The important components of composition is the matrix, selected mainly as concentrated glycerol and 1,2-propanediol and have high hygroscopicity and proper moisture retention. The matrix forms dry and not hard transparent scabs by binding with the water in wound exudation and amino acids above the plasma content, seals the wound rapidly so as to prevent the growth of bacterial in the air that fall into the wound after administration, and the bacteria cannot invade from the outside. At the meantime, because of the proper amount of Laurocapram or decyl methyl sulfoxide in the recipe, they can lead the effective medical ingredients in the formula with effects of antibacterial, nutritional, antioxidant and microcirculation to penetrate deep into the wound surface, thereby leading to the improvement of blood supply in wound tissue, blockage of the intestinal bacteria from reaching the wound by blood circulation, reduction of the early inflammation and re-injury on wounds and obtaining the ideal therapeutic effect of “both internal and topical repairments”. This is the delightful finding of the inventor in the practice of the present invention. It is believed that this will play an important role in exploring the molecular mechanism and cytology of burn wound repairment.

During long-term clinical practice, the inventor has treated a large number of patients with various skin wounds using the self-prepared pharmaceutical composition, involving about 1000 cases of general surgical dressing changes in clinic and common ward, treatment of emergency skin bruise, medication for burn and scald wound and treatment of bedsore, all of which have achieved effect obviously better than that of traditional wound medication, promoted wound healing, shorten the course of wound treatment, reduced the pain of the patients, saved the cost of medical treatment and relieved the workload of the medical staffs. The sources of the components in pharmaceutical composition of the present invention are all well-known ordinary medicines recorded in Chinese pharmacopoeia. The inventor extracted the pharmaceutically effective components by specific methods according to medical pharmacology in surgical field of combined traditional Chinese and Western medicine, determined the spectrophotometry in practice, and endowed them with a new prescription, whose effect of combined treatment of traditional Chinese and Western medicine in various skin wounds blazes brightly.

Example 4 Medical Cases of Treating Various Skin Wounds During Long-Term Clinical Practice

Case 1 Administrating Pharmaceutical Composition Formulation 3 of the Present Invention

For superficial II or deep II degree burn and scald wounds, cut out blisters, soak the cotton balls in medicinal liquid of composition, spread the cotton balls gently on the wound, and the liquid may be 1 mm thick. Expose the wound after spreading without dressing and there will be a transparent thin scab formed on the wound within 4-6 hr. In case of more exudation in the wound, apply the medicinal liquid again after 6 hr., apply the medicinal liquid up to three times on the first day. If the wound under the scab is clean and the transparent scab is dry on the second day, then apply the medicinal liquid once only onto the scab. If there is necrotic tissue under the transparent scab, moisturize the transparent scab with saline containing cotton balls and remove the necrotic tissue, and apply the medicinal liquid again. On the third day, when the transparent scab and the wound underneath are clean, continually expose the wound, and apply the medicinal liquid once only on the wound. If the necrotic tissue still exists under the scab, continue with the cleansing and liquid application.

The above treatment of superficial II or deep II degree burn and scald wounds can be healed on schedule and majority of the wounds will not be infected, as long as having the medical consultations without delay.

If the burn and scald wounds damage the full thickness skin or even damage the subcutaneous tissue, they should be treated according to the principle of III degree burn treatment. After granulation tissue grows to the level of normal skin, it is not necessary to make skin graft if the wound size is not big, and apply only the medicinal liquid of the composition. Wound granulation tissue can quickly form transparent scab, the wound swelling subsides and wound gradually heals beneath the scab. Because the wound heals quickly and the granulation tissue does not proliferate repeatedly, the scar from the granulation wound healing after applying the medicinal liquid of the composition of the invention is also relatively soft.

Present illness: The 2 year old girl Xu bumped into the legs of her mother who was then carrying a large bowl of stewed meat from the kitchen to the table. The high-heat broth spilled over the head of the daughter, and scalded her head and face. Therefore she came to the emergency. Examination: swelling and blister on the left ear, left forehead and left cheek, unable to open the left eye. Diagnosis: II degree burns on the left face, and the injured area accounts for about 2% of the body surface area. Treatment: cut out the blister and apply the medicinal liquid of the composition of the invention on the blister skin for twice on the day of injury. On day 2, cut out blister skin, continue applying the medicine on wound. On day 3, the wound was fully covered and protected by the transparent scab, no exudation and secreta. On day 4, the wound was dry, no infection, and medicine administration was stopped. On day 5, swelling on the left head and face and left ear gradually subsided; no pain when touched with cotton swabs. On day 10, the protective scab on the wound began to peel off, showing the primary healing of the wound. The follow-up after half a year showed no scar on face and left ear.

The two skin layers of ear are covered with a layer of cartilage and the surfaces are uneven. In the past, it was difficult to bind up during medication after scalding and the wound could be easily infected, making the treatment afterwards difficult. Applying the composition of the invention on the II degree scalded ear could fully cover the wound on ear without binding up, form protective scab rapidly, effectively eradicate infection and promote healing. II degree scald can become III degree scald once infected, and forms scars in different degrees after healing, leading to disfigurement. As long as the medicinal solution of the composition of the invention is used correctly in the early stage after the injury, there will be no infection and no scab formed on the II degree faciocervical scald.
